FASTENER FOR THE MEETING-RAILS OF SASFHES.

SPECIFICATION forming part of Letters Patent No. 275,706, dated April10, 1883.

Application filed October 13, 1882. (No model.)

To all whom it may concern.'

Be it known that we, ANDREW M. RANTZ, a citizen of Sweden, now residingat Oambridgeport, in the county of Middlesex and State of Massachusetts,and CHARLES L. EN- GELHARDT, a citizen of the United States, residing atBoston, in the county of Suffolk and State of Massachusetts, havejointly invented certain new and useful Improvements in Win- Io dow-SashFasteners; and we do hereby declare that the same are fully described inthe following specification and illustrated in the accom panyiugdrawings.

This invention relates to improvements in window-sash fasteners, and itis' carried ont as follows, reference being had to the accompanyingdrawings, in which- Figure 1 represents a plan view of the de vice shownin a locked position. Fig. 2 repzo resents a l'ront elevation of itshown as locked. Fig. 3 represents a vertical section on the line A B,shown in Figs. 1 and 2. Fig. 4 represents a side elevation of the deviceshown in the act of locking and securing the sashes together.

Similar letters refer to similar parts wherever they occur in thedifferent parts of the drawings.

In the drawings, a. represents the lower por- 3o tion Aof the outerwindow-sash, and b represents the upper portion of the inner windowsash,as usual. To the sash a is secured the striker a', provided on itsupright part with a slotted perforation, a, for the reception of the 3 5latch-lever, hereinafter to be described. To

the sash b is secured the plate c," provided with vertical bearings c'c,through the upper ends of which passes the screw, pin, or rivet 0"',as shown.

d is the latch-lever, journaled on the pin 0 between the bearings c c.The outer end of the latch-lever d is provided with a hooked projection,d', adapted to be swung into the slotted perforation a on the striker awhen the sashes a and b are brought in proximity to each other, and thusto effect a strong and secure lock between them by moving the latchleverd from the position shown in Fig. 4 to y the position shown in Fig. 3,which is done by depressing the `handle d, that forms a rear extensionof the latch-lever d, as shown in said ii gures. For the purpose ot'automatically retaining the latch-lever l in its locked position, asshown in Figs. 1, 2, and 3, we employ the lock cam or lever h, hinged ath tothe plate c, and provided with a thumb-piece, 7L, by means of whichit is operatedto be swung back against the rear portion ofthe latchleverd, as' shown in Figs. 1,2, and 3, and by means of which the latch-leveris prevented from being detached from the striker until the lock cam orlever h is swung to one side of the 1atchlever cl, which latter is thenautomatically caused to swing backward on its fulcruni-pin 0 by theinfluence of a suitable spring-wire, g, which is coiled around the pin0r screw 0', with its free ends resting against the rear' of thevertical bearings c o and its looped end pressing on the under side ofthe handle or extension d, as shown in Figs. 3

and 4.
